Conveying bagged goods with lumps

Conveying bagged goods with lumps.

Sometimes after long periods in storage, or due to the nature of the product, agglomerates can occur in bags and other storage containers. These can lead to blockages in the suction line during conveying or with negative influences in the downstream processes, because, for example, products can no longer be efficiently mixed.

For this reason the VOLKMANN lump breaker was developed. This can be mounted directly by a flange, for example under the RNT 180 (rip and tip sack loading station), and breaks down bigger agglomerates before being conveyed.



Installation under a big bag emptying station is also possible. Due to its design, the lump breaker is easy to clean and, due to our type model examination, it can also be used in dust and gas ex-zones.

The RNT180 has a buffer volume of approx. 180 liters and can be expanded to up to 400 litres, if required. In addition, the station can be used with sensors, various emptying aids or as a weighed version.

Contact our application experts for more information on the RNT180 product feed station or the lump breaker. >> Contact

Metal powder recovery made easy

Metal powder recovery made easy

Metal powder recovery made easy.

The PowTReX is a vacuum, transfer, sieving and recovery system for metal powders, developed for use in the ​​additive manufacturing (AM) industry. It is used to transport metal powder from, for example, 3D printers and unpacking stations with a high and constant suction power. The extracted powder is sieved and the material with the appropriate particle size can be automatically returned to the process.

The system has a small footprint of less than 1 m² and offers a high and stable material throughput. The PowTReX is a reliable, safe and easy to use system which utilises a HEPA filter for protecting against harmful substances. Installation in an EX zone 22 is also possible because it is an ATEX-approved system with type-tested components. It is operated using a touch display and one-button operation.

With this system, classification of all common types of metal powder and their alloys for additive manufacturing is possible (including stainless steel, aluminum, titanium, amongst others). Operation under fully inert conditions with a residual oxygen content of <1% is also possible, as is a complete closed loop solution for the inert gas recirculation.

Volkmann are proud to support Materials Solutions, based near Worcester in the UK, who are a Siemens business (since 2016). They utilise additive manufacturing (AM) technologies for the production of parts and tools for the aerospace, automotive and power generation industries worldwide using a variety of metal powders including Ni superalloys, Ferrous alloys and Aluminium alloys.

Materials Solutions has seen an increase in production which has led to the company’s expansion to a larger facility to accommodate additional AM machines to keep up with demand. Their new larger facility now boasts a greater selection of AM machines from various suppliers and in different sizes to increase their manufacturing flexibility. This increase in demand meant that a more efficient, reliable and versatile processes was required to help speed up the powder reclassification procedure between builds.

With some unsatisfactory powder reclassification systems trialled on site Volkmann was contacted back in early 2018 to help with an alternative solution and since then several systems have been supplied. The flexibility of the PowTReX has also enabled Materials Solutions to plan new powder handling and reclassification projects utilising Volkmann equipment which has enabled them to improve their powder reclassification process.

The PowTReX utilises a Volkmann vacuum conveyor to transfer powder from the build chamber to an ultrasonic sieve, via a dosing system which helps prevent overloading of the sieve mesh. With a sieving rate of approximately twice that to other available solutions on the market (using equivalent powder) the PowTreX is a good solution to help speed up the reclassification process.

Applications for the transport of powders and bulk materials with vacuum conveyors can be found not only in all known industries, but also in other locations around the world. The conveying often takes place inside buildings and production rooms, but Volkmann vacuum conveyors also work perfectly outside as well.

In addition to filling silos and conveying animal feed additives on fish farms, vacuum conveyors can even be found on ships which are used offshore for the generation of energy. Powdery additives are required during operation and these are delivered in bags which must therefore be emptied and then conveyed by vacuum.

Loading of powders in gas EX zones

INEX vacuum conveyors make it possible to transport bulk materials easily and safely within process plants for loading in to various vessels including stirred tanks or reactors. They enable powder transfer to all dust and gas explosion zones.

In this case, aluminum powder for the coating of metal parts was loaded into a reactor with flammable solvents, with an internal ATEX atmosphere classified at zone 0.

Double big bag emptying station

Double big bag emptying station

Double big bag emptying station for limited space unloading areas

Restricted unloading area solution: With this project a room with limited space has allowed us to develop a big bag emptying station with which two big bags can be emptied simultaneously.
The big bags are hung in harnesses and lifted using a winch. The mobile docking stations are pushed under the big bags and are equipped with devices for low-dust connection for emptying of the big bags. With two feeding adapters per docking station, the material to be conveyed is fed into the subsequent processes via a total of four VS250 vacuum conveyors, in this case loading four mixers.
The product unloaded and conveyed is sodium bicarbonate.
